Abstract:
A method and system for handover of a video call from a packet switched network to a circuit switched network by a first network entity associated with the packet switched network in a single radio environment is provided. A need to perform a video single radio voice call continuity (vSRVCC) handover from a packet switched network to a circuit switched network is detected during a video call session in the packet switched network. Accordingly, a vSRVCC handover request is transmitted to a second network entity associated with the circuit switched network for performing the vSRVCC handover of the video call session where the vSRVCC handover request includes vSRVCC capabilities of a user equipment (UE) associated with the video call session.
